Which element can be customized using CSS in Community Builder?

When using Community Builder in Salesforce, customization options are primarily focused on the appearance and user experience of the community. CSS (Cascading Style Sheets) is a powerful tool that allows developers and designers to modify the visual presentation of a community’s elements.

Font size and family are directly influenced by CSS, enabling users to change text aesthetics to align with branding or design specifications. This customization enhances readability and overall user engagement within the community. By applying CSS styles, such as modifying the font size or selecting a different font family, administrators can create a unique look and feel that resonates with their target audience.

The other options, such as user permissions, data source connections, and community member profiles, pertain to functionality and data management rather than aesthetic customization. Permissions govern what a user can do within the community, data sources connect to external systems for data retrieval or interaction, and member profiles provide user information; none of these elements can be styled or altered through CSS. Thus, only the font size and family elements are relevant to the capabilities provided by CSS in Community Builder.
